Abstract: 11,558. Ferranti, S. Z. de. May 19. Spindle e apparatus ; rollers and roller heads; creel arrangements; stopmotions building-motions. -Relates to improvements on the invention described in Specification No. 18,047, A.D. 1903. The material is drawn from bobbins 2, Fig. 1, the spindles of which are supported in water troughs 3 and carry square box-like floats 17, the resistance of which produces a drag on the material, the amount of the drag being regulated by varying the height of the water in the trough. The material is passed through suitable rollers and wound on to a spindle, bobbin, &c. by a rotating ring flyer, both the spindle and ring flyer being provided with airlubricated bearings, while one of them is driven by a suitable turbine, and the other is partially or wholly dragged round by the tension of the yarn. Oil-lubricating bearings such as those described in the prior Specification may, however, be used. The feed or draw rollers are driven from either the driven or the dragged part of the spindle apparatus. In the arrangement shown on the lefthand side of Fig. 1, the ring flyer b is driven and the spindle f is dragged and drives the rollers o through the wheels k, i and a shaft n, which is made in two telescopic parts to allow of the rise and fall of the spindle rail. In that shown on the right-hand side of the Figure, the spindle is driven and drives the rollers, while the ring flyer is dragged by the tension of the yarn. When a thread breaks, the dragged part of the spindle apparatus and the rollers, when driven thereby, automatically stop, and means may be provided for applying a brake to slow down or stop the rotating part. The spindle rails are supported on the ends of a lever t so as to balance one another, and are raised and lowered by a heart cam r and lever w. Figs. 4, 7, and 8 show three forms of ring flyer which may be used. It consists generally of a flange-strengthened tube C, mounted on a suitable support or bearing and driven by a Pelton wheel d or by a turbine C<1>, Fig. 8, of the Laval type, which is completely enclosed and shielded as shown. The Pelton wheel d is enclosed in a chamber 8, Fig. 4, which is closed above by a flange 10 on the ring flyer, so that the latter is partially or wholly supported during rotation by the air pressure. The weight of the ring flyer may, however, be supported magnetically, as shown in Fig. 7, in which flanges 14 on the ring flyer project opposite a casing 15 containing an electric coil 16. The support for the ring may be provided with flexible cushions b<2>, Fig. 7, and the ring is provided with a guide 6 near either its upper or lower edge, and may also have a cap or protector 12 to prevent the chafing of the thread and to exclude dust &c. from the bearing. The air supplied to the motor should be warmed to prevent the condensation of moisture, and should preferably be filtered to remove dust, as described in Specification No 25,134, A.D. 1904. When the guide 6 is formed near the lower internal edge of the ring, the ring serves to prevent the ballooning of the thread. In doubling-frames, the yarn is passed between conical rollers o, o<1>, Fig. 1, situated in a water trough, being guided by means of a curl on the end of a lever 29. which may be adjusted, for the purpose of regulating the speed at which the material passes between the rollers, by means of a toothed segment 26 and screw 27 operated by a hand-wheel. In the case of spinning &c. frames, the arrangement shown in Figs. 14, 16, and 18 is used. The front drawing-roller 31 is driven in either direction as desired by a disc-androller arrangement 32, 33, and drives the lower back roller 39 through bevel gearing 38 and a second disc-and-roller arrangement 40, the roller being adjustably secured to its shaft by means of a bent spring 48 which engages with a groove 49 in the shaft, and has a projection 50, which may be caused to engage with one or other of several notches in the bottom of the groove. The middle rollers 44 are driven through spur gearing from the back rollers. The upper rollers are attached by one end only to pivoted arms provided with dead weights or with weight hooks from which weights may be suspended.
